2112 logic cells, 111 I/O, 144-TQFP
The LCMXO2-2000HC-4TG144I is a Lattice MachXO2 FPGA packing 2112 logic elements and 111 user I/O in a 144-TQFP (20x20 mm) package. With 75 Kbit of on-chip distributed RAM and 264 LABs/CLBs, it handles glue logic, control-plane sequencing, and small-footprint state machines without an external CPLD.
Lattice lists this part as Active. The ROHS3 compliance covers the full substance restriction list including the four phthalates; no exemption certificate is needed for EU-market builds.
The 144-TQFP (20x20 mm) has a 0.5 mm pitch — a four-layer board with via-in-pad is not required; two-layer breakout is feasible for the inner rows if the fan-out is planned. The exposed paddle on the bottom (thermal pad) should be soldered to a ground-plane copper pour to pull heat from the core; a 2x2 thermal via array under the pad drops the junction-to-board thermal resistance by roughly 30% compared to a floating pad.
